Here’s a little Ultrasonic Ranger using the Parallax brand Ping ultrasonic transducer pair and the Parallax LCD display. Both are easy to use with the Arduino system. Just don’t try to supply more than…
Here I continue to demonstrate the versatility of the simple Arduino pot-voltmeter system. NOTE: I get scrambled when I describe the mosfet pin hookup. The Load has no connection to the mosfet gate, it…
I needed to record some time-temperature-power data over a long period of time. So I made this Arduino simple intervalometer to control the Canon camera through its external shutter release cable jack. The system…
A single RC servo and a couple of cheap CdS photoresistors make the Arduino “look alive” by making a simple light tracker. With just a few lines of code you can make the arduino…
CAUTION: Flickering lights: if you are prone to seizures or are affected adversely by strobes or flicker please don’t watch this video or build this project. I can’t be responsible for any adverse… or…
Color Organ featuring Software Fast Fourier Transform in real time. Please see the earlier Color Organ videos for the program sketch download location and the full credits to the folks who wrote the original…
This little gadget is primarily for Joule Thief research, where the relative brightness of an LED must be compared or monitored as conditions change. The TSL235A is a small sensor that converts light intensity…
Test de sortie PWN sur Arduino UNO et un potentiomètre Tinkerkit sur oscilloscope
here is The genset testing thread: http://open-source-energy.org/forum/showthread.php?tid=383 the Arduino code is also there. tinman’s video:
I changed the code a little bit to show the resolution of the ultrasonic ranging method used by the Arduino/Ping combination. I think that the resolution is about 1-2 mm at the distance I…
